摘要

摘要:
为明晰超宽带电磁脉冲对引信的干扰和损伤影响，确定引信-电磁脉冲效应的阈值区间，针对当前引信-电磁脉冲效应数据样本少，难以准确评估引信的抗电磁脉冲能力的难题，建立了马尔可夫蒙特卡罗估计的引信-电磁脉冲效应阈值分析模型。通过构建的超宽带电磁脉冲模拟器的引信效应测试系统，对典型引信进行辐照试验，得到引信-电磁脉冲的效应规律及干扰阈值。试验结果表明：引信通信故障的效应阈值均值为28.262 kV/m，均值的95%可信区间为（27.390，29.129）kV/m；方差的后验期望估计为1.867 kV/m，方差的95%可信区间为（0.834，4.182）kV/m。所提模型可用作多种引信的电磁脉冲效应阈值估计，为提高引信的抗电磁干扰能力提供理论基础和试验手段。

Abstract:
In order to clarify the interference and damage effects of ultra-wideband electromagnetic pulse on fuze, the threshold interval of fuze-electromagnetic pulse coupling effect is determined. It is difficult to accurately assess the anti-interference ability of fuze in the electromagnetic pulse environment because the fuze-electromagnetic pulse effect data samples are few. To solve this problem, in this paper, a threshold analysis model of fuze-electromagnetic pulse coupling effect is established based on Markov-Monte Carlo estimation. The fuze effect test system is constructed by a typical ultra-wideband electromagnetic pulse simulator. The fuze-electromagnetic pulse effect law and interference threshold are obtained, through the electromagnetic pulse irradiation test of the typical fuze. The test results show that the mean value of the fuze communication failure threshold is 28.262 kV/m, and the 95% confidence interval is (27.390, 29.129) kV/m; the posterior expectation of variance is 1.867 kV/m, and the 95% confidence interval is (0.834, 4.182) kV/m. This method can be used to estimate the electromagnetic pulse effect threshold for various fuzes, and provide the theoretical foundation and test means for improving the fuze's ability of anti-electromagnetic interference.
